Prepare for release version 1.5.2

- Add: Setting to enable/disable the mouse-over box
- Add: Current WordPress Theme to the Diagnostics sub page
- Add: ManFisher note in the "other Plugins" sub page
- Update: Removed unnecessary hidden inputs from the Settings page
- Update: Merged public CSS files to reduce the output and improve the performance
- Update: Translations (EN and DE)
- Bugfix: Removed the 'trim' function to allow whitespaces at the beginning and end of each setting
- Bugfix: Convert the footnotes short code to HTML special chars when adding them into the page/post editor (visual and text)
- Bugfix: Detailed error messages if other Plugins can't be loaded. Also added empty strings as default values to avoid 'undefined'
